Page 162 - A body immersed in a liquid is buoyed up by a force equal to the weight of the liquid displaced by it.
Page 163 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 23 - Every body continues in a state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by a force impressed upon it.
Page 7 - The FORM of a body is its external shape. Bodies may have the same magnitude and be very different in shape ; they may likewise be of the same form and yet be of very different magnitudes. Impenetrability. 7. IMPENETRABILITY is that property by virtue of which no two bodies can occupy the same place at the same time.
Page 218 - ... is made to indicate its own temperature without possibility of mistake. Liquid Thermometers. In the most common form of thermometer, temperature is measured by the expansion of mercury in glass. On the end of a glass tube of very fine bore, a bulb is blown (see Fig. 1), and the bulb and part of the tube are filled with mercury. The whole is then heated until the mercury completely fills the tube, after which it is sealed and allowed to cool. The space in the tube above the mercury is thus entirely...
Page 163 - The BAROSCOPE consists of a beam like that of a balance, from one extremity of which is suspended a hollow sphere of copper, and from the other extremity a solid sphere of lead. These are made to balance each other in the atmosphere. If the instrument be placed under the receiver of an air-pump and the air exhausted, the copper sphere will descend.
Page 340 - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
Page 192 - If two clocks, for example, with pendulums of the same period of vibration, be placed against the same wall, and if one of the clocks be set going and the other not, the ticks of the moving clock, transmitted through the wall, will start its neighbour.
Page 338 - LAB, is the plane of incidence. The angle that the refracted ray makes with the normal at the point of incidence is called the angle of refraction, and the plane of this angle is the plane of refraction / thus, the angle KA C is an angle of refraction, and the plane of this angle is a plane of refraction.
Page 249 - The heat which is expended in changing a body from the solid to the liquid state, or from the liquid to the gaseous state, is called latent heat.
